Hi, I'm new to this and really need your help with this question. Genetics are not my strong point in bio. Please help me with this. Thanks

1. A backyard gardener had seeds from a variety of peas that were hybrids (heterozygous) for red flower colour. In peas, red flower colour (R) is dominant to white flower colour (r). If these plants were allowed to self-pollinate and produced 1284 seeds, use a Punnett square to predict the genotypic and phenotypic rations for the F1 and F2 generations.

If they were all heterozygotes, they must be Rr. That should be easy. Now you have to do Punnett:

.... R .. rR . RR . Rrr . Rr . rr

thus you see that F1 will be genotypically RR : Rr : rr - 1 : 2 : 1. It should be easy to make phenotypic ratio from that.F2 generation will be pretty hard, because one can combine all three of them for each parent.

Would 25% be Red, 50% Pink and 25% White?? Or would it be 3/4 Red because red is the dominant and 1/4 White? Sorry im just trying to understand this. Im still not sure what to do for the F1 F2 generations.
